Customer #24850 on COM-10017 - LED - RGB Diffused Common Cathode (100 pack)Customer #24850urn:uuid:558b5a89-7d4e-bb8f-8c6d-7a88508e5e0f2011-04-30T08:11:45-06:00<p>There appears to be a fault in the infosheet that is included with this pack of SparkFun diffused LED&rsquo;s: the example circuitry with AA battery four pack has the drawing of the LED mirrored. The &lsquo;flat side&rsquo; is now opposite of where it should be and the long pin, that should be the cathode, is now denoted &lsquo;G+&rsquo;. The whole LED drawing should be mirrored over the horizontal axis to correct this error. Also, compared to the datasheet linked on this page &lsquo; R+&rsquo; en &lsquo; B+&rsquo; seem to be swapped.</p>arduino1324 on COM-10017 - LED - RGB Diffused Common Cathode (100 pack)arduino1324urn:uuid:2d6fab12-2259-d1ac-7b43-7876b21f00552011-03-22T20:16:20-06:00<p>Oh yah, didn&rsquo;t see that. (and yah i know what a common anode and cathode it btw) lol but thanks for pointing that out</p>mk_like_whoa on COM-10017 - LED - RGB Diffused Common Cathode (100 pack)mk_like_whoaurn:uuid:c1b05986-cbbb-ecf0-85d4-fc195f690e242011-03-15T23:21:28-06:00<p>That link is for common <strong>anode</strong> LEDs, instead of these common <strong>cathode</strong> LEDs.<br/>
There&rsquo;s an clearer explanation of what this means on the <a href="http://arduino.cc/forum/index.php/topic,50777.msg362215.html#msg362215" rel="nofollow" >Arduino forum.</a>.<br/>
It&rsquo;s not a huge thing, but there&rsquo;s definitely a difference. Working with anode LEDs will mean some counter-intuitive coding, and possibly a significant amount of time spent inverting values after copying/pasting existing code.</p>arduino1324 on COM-10017 - LED - RGB Diffused Common Cathode (100 pack)arduino1324urn:uuid:d1d066d8-a225-594e-22d9-577f15ff20452011-02-19T07:24:38-07:00<p>Buy them here you guys, you can save $35<br/>
